To all Qu-0m 'it may Conce/ML.

lized to torce a liquid troni a lower to av higher level, the device being' adaptable as a substitute tor a pump, and its objects are, primarily, to provide means tor siphoning waste water from basements and excavations, and to eliminate the use ot ay pump generally required tor this purpose.

Other objects are to provide means for controlling the fluid which serves to create the suction for draining such basement or excavation ot the accumulating' water, to provide means whereby the suction 'torce is quickly established, and thereafter main? ".iined, to provide means for regulating the ilow or1 liquid which is to be pumped or forced to the higher level, and to provide a device of this character which is tree from projections which would interfere with the convenient handling ot the `device in limited spaces.

My invention is a device of the general character noted, that embodies the peculiar and novel construction of parts hereinafter more tully described, specitically pointed out in the appended claims. and illustrated in the drawings. Steam and water under pres-` sure may be considered substantially, as equivalents tor generating the motive force :tor the raisingand forcing or' liquids.

In the drawings, Figure 1 is a side view ot my improved siphon. Fig. 2 is a central longitudinal section ot the same. Fig. 3 is a cross-section on line 3 3, of F 2. Fig. 'si is a side view showing` the device connected to a hose. Fig'. 5 is a detail view' ot` the supporting' ring'. Fig. 6 is a perspective detail view ot the expander for the flexible elements. Fig. T is fragmentary and enlarged detail view showin@r the spreading elements in expanded position.

Referringto the drawing, the practical arrangement of my invention comprises the casing" 11, merging at the outer end 12, in a taperin` nozzle 13, exteriorlyv screw-threaded tor attaching a discharge hose 1st, Awhich conveys the water or liquid to the desired point of delivery. The casing is extended toiorm the projecting inner nozzle in chamber' '16,. which is provided ,with inlet suction openings 17, in the outer wall of casing 11, the openings being covered by screens 18, serving `to prevent entrance of i' material which would clog the chan'iber and nozzle.. f. -Y

.n integral diaphrao'm vwall 19, is provided with an orice 20, opposite opening 21, in inner nozzle 15, and coaxial therewith, A. sleeve 22, having screw-threaded connection with casing 11, vmay be `rotated to open and close suction openings 17, and may be adjusted to any desired point, thereby partly closing the apertures `in accordance with the pressure ot the iiuid discharged 'from lorihce 20. At its opposite end, casingl 11 is provided with the interiorly threadedextremity 22%, into whiclris screwed themembert, arovided with a central valve seat 25,1and'at its opposite extremity, with a. stuffing box 26.

Valve llemler 27, is brevi/led with an enlaro'ed end 28, interiorly threaded' i'or al hose connection 29, which provides the actuating iiuidunder pressure. The valve member 27, terminates in a tapered end BO, adapted to engage with valve seat 25, inv closed position. The valve member is rotated to' seat ott the actuating` fluid. y j Y i YWhen valve 30 is inl itstully open position, the actuating iluid is delivered through oriiice 2O in a relatively narrow jet. y In the fully open position ot valve 30,l the ilenible elements 31, on theiend thereof, lie closely the end 30 in its valve seat; andl thereby shut from orifice is discharged in thev center ot orifice 2l. (Thismay tend toprevent immediate priming of the device.) That the seltprim'ing operation will` talre place speedily, l have' provided flexible elements 31, fixed to the end of valve member A ring 32, retained by packing 33, supports theactuating element 34, tor expanding,I or spreading elements 31. As elements 31 are expanded, and while they do not fully closethe lorifice Q0, the torce jet is correspond-i-iigly eX-` panded within the' delivery nozzle, thereby quickly creating sufficient suction within chamber 16. The expand-ing `element.,3a is rotative relative to supporting ring 32, but is Aretained againstl longitudinal ,movemenig while elements 31, advance longitudinally luponV rotation ot valve-member 27, and may therefore be `adjusted tov spread the torceA jet within-the del-iverynozzle.

together, and thus the steam jet issuing` The entrance to the discharge tube has a certain area. for the liquid which is to be pumped, to enter such discharge tube. .lfv the discharge tube area be so large in pri portion to the actuating et, no priming will occur, and if the discharge tube area be relai tively very small in proportion to the actuating jet, the capacity of the device for serv-A ice as a pump, is reduced accordingly. The expanding` elements herein described serve to expand the jet at the entrance to the discharge tube to cause immediate suction therein. After the operation has started, the area of the jet is then. reduced by adjusting the spreading` elements ont of the path of' the jet, and the resulting increased velocity of' the liet serves to mor-.fe the increased amount of liquid that enters around the jet at the entrance to the discharge tube.

ln an ordinary device not having my jetspreading elements, on the emission of 'the jet from the orice, the saine may travel within the discharge tube some distance, before spreadingl suidiciently therein to cause the suction required for operation a pump, and, at the point Where the jet has filled the discharge tube, its velocity is so reduced, that priming of the device does not readily occur. With my jet-spreading elements serving' to expand the jet at the entrance to the discharge tube, the area for the liquid to be pumped is relatively much re duced, and the velocity of the jet is, at this point, approximately at its maxiinunnthus causing` the device to become instantly primed.

1t is to be understood that when the valve 30 is fully closed upon its seat, there Will be no jet issuing from orifice S20, but the issuing jet is expanded upon adjustment of the expandingelements 31.

1n use, the device being` connected to the fluid pressure supply and with the delivery hose, is then submerged in the liquid which is to be forced to a higher level. if the fluid actuating pressure be very low, then the sleeve is adjusted to reduce the area. of the inlet or suction openings. @n the other hand, 'the fluid actuating` pressure being high, the sleeve is adjusted to its fully open position. The fluid pressure may be othew wisc regulated by turning the adjustable valve'. Atdiustnient may also be made 'for expansion of the injector iet which passes from the jet orice into the delivery nozzle. The main casing and controllingnozzle or valve are detachable, and the device may be used Without the controlling valve.
